The SSL certificates that are used for wireless access expired on Saturday (August 15/09). At that time the Thawte certs were replaced with GlobalSign certs.
Blackberry (and perhaps other devices) have the CA certificate coded in the 802.1x authentication profile. This setting will need to be changed:
Previous Setting: Thawte Premium Server..
Required Setting: GlobalSign CA 2014
SSID remains as ‘uw-secure’ and Security-type is unchanged with ‘PEAP’
